1980 240D wont start after fuel filter replacement?
I replaced both the in-line and spin on (secondary filter) Car wont start. I was told to fill the spin on filter with Automatic Transmission Fluid. That didn't help. Doesn't even try to start, just turns over. I loosened the nut on top of the filter assembly and used the had pump to bleed the air out but didn't help what's even worse is that my in line filter turns black and chokes off the fuel supply about every 1000 miles or less. Do the fuel tanks on these cars get mucky or is there another filter I am unaware of??? Thanks for any help.
filling your filter with ATF? I don't remember doing that last time, I just read to lubricate the top right with a dab of diesel and filing the actual filter with diesel to remove as much air before priming the engine pump until diesel starts to spill over.
But other than that, yes the fuel tank filter is often a culprit for a few members, but wouldn't/shouldn't be disturbed by you just changing the fuel filters.
Check your inline fuel filters for excess bubbles or discoloration.
Rather than go into verifying the hand pump works or not, or loosening injector lines to purge air etc. etc. Have someone crank over the engine while you spray WD 40 into the intake. Just remove the air filter lid and spray while someone cranks the engine over. It will start, run rough for a few seconds then smooth out. Next time restart it after each filter. WD 40 is basically kerosene.
ATF is too thick to put in the filter. I did that once to mine too, and it took a long time to get started again. I just kept priming like crazy and turning it over, eventually it fired up.

Oddly enough, that was what the local MB mechanic recommended to me. I never tried it though. I think the Lubro Moly diesel purge works much better for cleaning the injectors. Some people add a quart of transmission fluid to each tank of fuel. That dilutes it enough so that there should be no starting or performance issues.
If you think your internal fuel tank filter is clogged, the simple way to deal with it is to remove the fuel cap, remove the black fuel line that attaches to the input side of the plastic, secondary fuel filter and using an air pressure hose, blow a couple of quick blasts in that fuel line - if there is anything in clogging the filter in the tank, that will clear it.
